Google’s venture to beam the Internet to remote areas of the world via balloon has hit a legal snag in Sri Lanka that could see the project abandoned on the island, a minister said Thursday.

“Project Loon” uses roaming balloons to beam Internet coverage and planned to connect Sri Lanka’s 21 million people to the web, even those in remote connectivity black spots.

But just a year after testing began in Sri Lanka regulators have been unable to allocate Google a radio frequency for the airborne venture without breaching international regulations.

Communications minister Harin Fernando said the Geneva-based International Telecommunications Union (ITU) was opposed to Google using the same frequency as Sri Lanka’s public broadcasters to provide its Internet.

“It boils down to a legal issue,” Fernando told reporters in Colombo.

“The government as well as Google are lobbying the ITU, but if we fail there’s a risk Google will go to another country that is not bound by these rules.”
